Preheating is performed at a predetermined temperature while the preheating chamber 1 is evacuated. After the preheating is completed, the gate valve 4 is opened, and the sample A is carried by the cylinder 7 into the main heating chamber 2, which has been previously evacuated in the same manner as the preheating chamber 1. Sample A is in main heating chamber 2
After being carried into the chamber, the gate valve 4 is closed, and the sample A is heat-treated in the main heating chamber 2 at a predetermined pressure and temperature. After the right heat treatment is completed, the gate valve 4' is opened, and the sample A is carried by the cylinder 7' into the cooling chamber 3, which has been previously evacuated in the same manner as the main heating chamber 2. After the sample A is carried into the cooling chamber 3, the gate valve 4' is closed, gas is introduced into the cooling chamber 3, and a predetermined cooling is performed. After cooling the right side, the inside of the cooling chamber 3 is brought to the same pressure as the atmospheric pressure, the opening/closing door is opened 5 degrees, and the sample A is transferred to the outside of the furnace by the cylinder 7.
The above is a general process, but it may be tempered to improve toughness. In the case on the right, in order to carry out the above-mentioned example, it is possible to return the sample A to the main heating chamber 2 after cooling, or to connect a heating chamber after the cooling chamber 3.

、効率的な半連続処理を行える。The sample loading/unloading chamber is a chamber for loading and unloading the sample, and is equipped with a gate valve.Another embodiment of the present invention will be described with reference to FIG. While sample A is being heat-treated, sample B, which has already been heat-treated, is cooled with circulating gas by a quenching part 15 that has a heat exchanger and a gas circulation blower attached to the transfer chamber, and is taken out from the sample inlet/outlet 14. Then, the next sample is loaded. When the heat treatment of sample A is completed, the moving mechanism moves the loaded sample to position B and the loaded sample to position A. Compared to the batch type, which performs heat treatment and cooling in a furnace, it allows for more efficient semi-continuous processing.
